Get the free DIRECT SHEAR TEST

A direct shear test is a laboratory or field test used by geotechnical engineers to measure the shear strength properties of soil or rock material, or of discontinuities in soil or rock masses.

How to fill out direct shear test

How to fill out direct shear test

1. Step 1: Set up the direct shear apparatus and ensure that it is stable.
2. Step 2: Prepare the soil sample by compacting it into the shear box.
3. Step 3: Attach the shear box to the direct shear apparatus.
4. Step 4: Apply normal stress to the soil sample by placing weights on the shear box.
5. Step 5: Apply shear force to the soil sample by moving the shear box horizontally.
6. Step 6: Measure the displacement and shear force at regular intervals.
7. Step 7: Continue applying shear force until failure of the soil sample occurs.
8. Step 8: Record the maximum shear force and displacement at failure.
9. Step 9: Repeat the test with different soil samples if necessary.
10. Step 10: Analyze the data obtained from the direct shear test to determine the shear strength parameters of the soil.
